In the present embodiment, multiple grooves 322 are equipped with the diverse location of the outer circumferential surface 321 of cam 320 so that when first
When plate folds with the second plate or is expanded to corresponding diverse location, locking can be realized, to adapt to different angle expansion
Need.In addition, first connecting rod 341, second connecting rod 342 that the connecting rod 340 of the present embodiment includes are tabular straight-bar, elastic component
360 use reed, and the reed is located at the side of connecting rod 340, and its one end is connected with locating shaft 350, the other end and fixing axle
370 offset, and when locating shaft 350 is in first state and the second state, which is in impaction state, make positioning to provide
Elastic force of the axis 350 away from fixing axle 370.In first state, the direction which pushes locating shaft 350 to rotation axis 330 makes
It is close to the outer circumferential surface 321 of cam 320；In the second state, which is pushed into locating shaft 350 in groove 322, realizes lock
Tightly.
According to the folding of the plate object of the present embodiment and expanding unit, set on the diverse location of the outer circumferential surface 321 of cam 320
There are multiple grooves 322 so that there is the locked position of multiple angles expansion, practicality is richer between its two boards part being connected
It is rich.Locating shaft 350 is close to the outer circumferential surface 321 of cam 320 using elastic component 360, predetermined angular is unfolded between two plates that are connected
When locating shaft 350 can roll into or slip into the groove 322 on the outer circumferential surface 321 of cam 320 so that locking be easier, position
It is more accurate.In addition, when using various sizes of cam, original connecting rod 340, locating shaft 350 and elastic component 360 etc. can be with
It is continuing with, it is not necessary to change whole plate object folding and expanding unit, so as to simplify design efforts would.
The present invention also provides a kind of solar energy sailboard structure, it is used for spacecraft, including：First windsurfing；Second windsurfing；
And the plate object of any of the above-described embodiment of the present invention folds and expanding unit, by the way that the plate object is folded and expanding unit
Cam is fixed with the first windsurfing, and the second end of connecting rod is fixed with the second windsurfing, it is possible to achieve the second windsurfing and the first windsurfing are around institute
State that rotation axis folds or expansion and realizing is locked in predetermined expanded angle, be easier during locking, locked position it is more accurate.To too
When positive energy windsurfing structure is designed, whole plate object folding and expanding unit need not be changed by changing the size of cam, more square
Just design, it is cost-effective.
